commands/i386/pc/sendkey: Fix "writing 1 byte into a region of size 0" build error
Latest GCC may complain in that way:
commands/i386/pc/sendkey.c: In function ‘grub_sendkey_postboot’:
commands/i386/pc/sendkey.c:223:21: error: writing 1 byte into a region of size 0 [-Werror=stringop-overflow=]
223 | *((char *) 0x41a) = 0x1e;
| ~~~~~~~~~~~~~~~~~~^~~~~~
The volatile keyword addition helps and additionally assures us the
compiler will not optimize out fixed assignments.
